Preheat oven to 350 degrees. In a large mixing bowl, combine cake mix, pudding, oil, milk, sour cream and eggs. Beat until all ingredients are well moistened. Pour the batter into 2 or 3 prepared cake pans (depending upon how thick you want your layers to be). Bake for 25 minutes or until a toothpick inserted into the middle comes out clean.

Allow the cake to cool completely before frosting with packaged cream cheese icing. Garnish with white chocolate chips, if desired. You can also drizzle with a little of the prepared icing that has been colored with food coloring.
